REPORT OF THE PROFESSOR OF ETHNOLOGY AND 

 ARCHAEOLOGY. 



I have the honor to report that during the year 1885 a course 

 often lectures was delivered in the hall of the Academy, on the 

 ethnology and archaeology of America. They were illustrated 

 with maps, drawings, and by means of specimens obtained from 

 the various collections within the rooms of the Academy. The 

 lecture hall was usually well filled, and quite as much interest 

 was manifested X>y the audience as could be expected from the 

 nature of the topics discussed. 



The collections of the Academy in this department are sub- 

 stantially the same as noted in the last report. It would be easy 

 to increase them, were there ample accommodations for the 

 favorable display of objects. 



Respectfully, 



D. G. Brinton, M. D., 

 Professor of Ethnology and Archaeology.
